PRACTICAL STERILIZATION AND DISINFECTION 155 



As a rule it may be stated that chlorine gas liberated from 

 the above sized cone will be sufficient for disinfecting 5200 

 cubic feet of air space." 



Liquid manure, teachings, etc., where collected are thor- 

 oughly disinfected by chloride of lime applied in the pro- 

 portion of 2 parts to 1000 of fluid. 



Vehicles may be thoroughly washed with 2 per cent, for- 

 malin solution, or if closed space is available, subjected to 

 formaldehyde gas disinfection, after cushions, hangings, etc., 

 have been removed and washed with the disinfectant.

 tion. The small cylinder at the side is the generator. 



Harness, brushes, combs should be washed with a solution 

 of formalin, carbolic acid, or creolin as given under these 

 topics. 



Washable articles should be boiled, dropped into disinfectant 

 solutions as soon as soiled, and then boiled or steamed. 



Unwashable articles — burn all possible. Use formaldehyde 

 gas method in a closed receptacle (Fig. 111). 



Stock cars — the method described for stables is applicable 

 here. 



Animals, large and small, may have the coat and surface 

 of the body disinfected by washing with 1 to 1000 bichloride 

 or strong hot soapsuds to which carbolic acid has been added 

 to make a 5 per cent, solution; they should then be given a 

 good warm bath.
